net/mlx5: Apply rate-limiting to high temperature warning

Browse Source 
[ Upstream commit 9dd3d5d258aceb37bdf09c8b91fa448f58ea81f0 ]

Wrap the high temperature warning in a temperature event with
a call to net_ratelimit() to prevent flooding the kernel log
with repeated warning messages when temperature exceeds the
threshold multiple times within a short duration.
